Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond sometimes I get your replies late so there may be a delay in my response.

Can you get the complete model number off the tag on the unit?

Customer: replied 1 year ago.
the model is ZISB42D and SN is GMO380030 GE monogram series

There are a couple more letters after the D I need them

Customer: replied 1 year ago.
The unit is 19 years old and the tag inside is unreadable. I have GE service receipts that reflect model # ***** for an icing kit repair and ZIB42DWR for a compressor replacement

Ok the most likely issue that is causing that problem is a bad thermostat, the contact wears out in the operating thermostat, then the unit will shut down for extended periods without turning back on then it you check it or turn the dials or bump it it may run again fine. The issue is the parts for that unit are mostly obsolete. Here is the thermostat number, but it is also obsolete. It may be time to check for a new one.
